The Seahawks placed defensive tackle Bryan Mone on the reserve/COVID-19 list on Monday, the seventh player on their 53-man roster, and ninth, practice squad included, to go on the COVID-19 list since last Thursday.
Mone, who left last week's game with a knee injury, has not practiced since being a limited participant on Wednesday, so his status was in question for Tuesday's game against the Rams even before going on the COVID-19 list.
The Seahawks placed starting receiver Tyler Lockett on the COVID list last Thursday along with running back Alex Collins, then on Sunday they placed six more players—four on the 53-man roster and two on the practice squad—on the list, including starting cornerback D.J. Reed and right tackle Brandon Shell.
The Seahawks were originally scheduled to play the Rams in L.A. on Sunday, but that game was moved to Tuesday due to a Rams COVID-19 outbreak last.
